Abstract

Abstract: In order to evaluate the antioxidant activity of persimmon peel extracts (PPE) in vitro, different antioxidant evaluation assays and a mouse model of liver mitochondrial damage induced by Fe2+-H2O2 or Fe2+-VC in vitro were used. The results showed that PPE possessed excellent total antioxidant activity, reducing power, inhibitory activity against lipid peroxidation and radical scavenging activity. The IC50 values against DPPH, superoxide anion and hydroxyl radicals were 57, 137μg/mL and 425 μg/mL, respectively. In addition, PPE could significantly protect mitochondria from lipid peroxidation, swelling, protein oxidation and the reduction of ATPase activity in rats. In conclusion, the current study showed that PPE can resist oxidation obviously in vitro and be utilized as a new natural source of antioxidant.

Key words: persimmon peel, antioxidant, free radical, mitochondria
